Remote Controlled Cart Project


I need components suggestions regarding my project. I am building a remote-controlled delivery cart that could carry 50lbs or less. I am planning to use Arduino Uno and DC motors. What is the best motor control driver I could use? Should I use an L298N? The cart should have a speed of 5km/h.


4 x Arduino Uno
4 x DC Motors: 12V 80W each
Battery source?

Any suggestions?

Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

Is this your first Arduino, controller project?
Can you please tell us your electronics, programming, arduino, hardware experience?

Have you done your calculation of how high the start/stall current of the motors will be.
This will help you choose your motor driver.

Are you motors geared, can you please post spec/data link please?

Why do you think you need four UNOs, probably only two, one for the TX and one for the Rx.

Thanks.. Tom... :slight_smile:

I'm not sure what DC motor to choose. I was thinking powerful enough to carry 50lbs. I did my calculations, I need at least 320 Watts of power. I can split this into 4 wheels. Maybe 80W each. What stall current should I use? Possibly 7Amps?

Its not a case of carrying the weight, it is the case of getting it moving and keeping it that way.
Will there be any inclines?
I have no experience with mobile applications like yours, but you may have more suggestions in the next 24hours as the world turns.

Search on Arduino, and Wheel Chair Motors

LOTS of people using those. You get a platform, wheels, battery holders and sometimes useable motor drivers.

HERE is an example using wheel chair motors/transaxle on a different project...
